Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).

Privateer Viper team sets a 7:03.45 time at the Nurburgring (UPDATE)

Update: The Viper record crew have uploaded video of the official lap. According to the group's Facebook page, they believe a sub-7 minute time is possible. They will try to return to the 'Ring in August when there are some open slots at the track, and they will be raising money to pay for a return trip. The group of Viper fans we told you about last week now have their first Nurburgring record attempt out of the way according to Road & Track. The automotive publication reports the team set a time of 7:03.45 with a 2017 Viper ACR. That's a bit over 8 seconds faster around the 'Ring than the previous-generation ACR. Unfortunately, the time puts it behind the Porsche 918 Spyder's 6:57 time and the Lamborghini Huracan Performante's 6:52 time. We've reached out to the privateer team for additional info on the attempt, and whether they will be able to make more attempts on this trip. We will update this as soon as we hear back. The team making these attempts got its start with a GoFundMe campaign to pay for a trip the Nurburgring to set times. The reason for this trip was the fact that Dodge never took this generation of Viper ACR to the famed German racetrack, despite going around setting fast laps at North American circuits. With funding from donors, sponsorship from Kumho Tires and Prefix, and provision of two Viper ACRs from Viper Exchange and BJ Motors, the team was able to make the journey.Related Video: This content is hosted by a third party.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
